Question

I am trying to make my code compare two vectors. Both vectors will be compared with the same amount of ints. I want it to output Yes if all the ints in redCups are less than GreenCups. And output No if any cup at all in the redCups is larger than greenCups.

Am I tackling this right?

    bool beb = true;

    for (int i = 0; i < numCups; i++)
    {
        if (redCups[i]<greenCups[i])
        {
           beb = false;
        }
    }

    if (beb == true)
    {
        cout << "Yes" << endl;
    }
    if else ( beb == false)
       cout << "No" << endl;

You can use the std::equal algorithm to compare each pair of elements from two containers. By default it returns true if all pairs are equal but it’s easy to test each pair for less or less_equal instead.

bool beb = std::equal(redCups.begin(), redCups.end(), greenCups.begin(), std::less<int>());
